The FAA is adopting a new airworthiness directive (AD) for certain Umlaut Engineering GmbH (previously P3 Engineering GmbH) HAFEX (Halon-free) hand-held P3HAFEX fire extinguishers (fire extinguishers). This AD was prompted by reports of a quality control issue on certain fire extinguishers, where the spindle geometries of the fire extinguishers were found to be out of tolerance. This AD requires removing affected fire extinguishers from service. The FAA is issuing this AD to address the unsafe condition on these products.
(1) Within 12 months after the effective date of this AD, remove each fire extinguisher identified in the introductory text of paragraph (c) from service.
(2) As of the effective date of this AD, do not install a fire extinguisher identified in the introductory text of paragraph (c) of this AD on any aircraft.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
